Data of the Fukushima Daiichi

Jan. 04, 2013 (Friday)

The serious situation remains unchanged, in that workers still have to cool nuclear fuel with water at the melted-down No.1 to No.3 units of the No.1 Fukushima Nuclear Power Plant.   /.      For your information, this blog continues to record temperatures measured at the lower part of the pressure vessel of each unit.  Temperatures between Dec. 29 and Jan. 04 are posted on the following page.(Source: TEPCO)

Data will be posted each Monday from now on.The following are the results of observations during the Dec.9 week.

On Dec. 13, Cs-137density was found to be 3.3 Bq/L in the sumples collected 30 meters north of the Unit 5-6 outlets.

On Dec. 15, Cs-137density was found to be 1.6 Bq/L in the sumples collected 30 meters north of the Unit 5-6 outlets. 

On the other five days, no noticeable amount of radioactive iodine or cesium was detected from sea water near the outlets of the Fukushhima No.1 plant.  Radiological dose in the air of the plant site, meaured yesterday,is posted on the following page. (Source: TEPCO)
